If you commute to work via BART, today is an attitude check for you. Will news that the system's trains are running half an hour late
induce you to get out of the house that much earlier? Or do you now have time for that extra cup of coffee?
In any event, your shot commute stems from a 4:42 a.m. incident in which an airport-bound train
hit a stretch of tracks between 24th Street Station and Glen Park with no power. That problem was remedied within two hours, which likely resulted in more than a few missed flights and "residual delays" of up to half an hour or more.
The cause of the outage is unknown.
